retardants some special significance

Most plastics are flammable . With the plastic in the construction, furniture, transportation, aviation , aerospace , electrical and other aspects of the widely used to improve  fluorescent brightener the flame retardancy of plastics has become a very urgent issue. Inhibiting polymer flame retardant is a class of flammability additives, they are mostly of the Periodic Table Ⅴ, Ⅶ Ⅲ elements and compounds ; especially phosphorus , bromine , chlorine , antimony and aluminum compounds. Sub- additive flame retardants and reactive types . Flame retardant halogen-containing primarily phosphate and phosphate, a halogenated hydrocarbon , antimony oxide , and aluminum hydroxide . Advantage is easy to use and adaptable . However, the PVC profile stabilizer  addition of capacity of 10 % to 30% , often affect the performance of plastics . Reactive flame retardant containing the elements actually monomer, it has little effect on the plastic properties . Common reactive flame retardants , halogenated anhydrides such as for polyesters , for epoxy resins of tetrabromobisphenol A, and phosphorus for polyurethane polyol. Initially flame retardants used in the U.S. , after the 1960s, the amount of surge current usage after plasticizer. Consuming most varieties of plastic flame retardant polyvinyl chloride, polystyrene, polyurethane foam , unsaturated acrylic processing  polyester , ABS resin and polypropylene.
Most plastic is flammable , its products, which brought a lot of application security risks. Precisely, flame retardants, flame retardants known as more appropriate , because " flame " contains two meanings flame retardant and smoke suppression , compared with the broader concept of flame retardants . However , long time, people have become accustomed to the concept of use of flame retardants , so the current literature is actually referred to in the flame retardant and smoke suppression effect of functional additives in general.
